A chilling new audio clip that surfaced over the weekend purportedly shows the police officer who fatally shot Walter Scott earlier this month laughing nervously about the incident shortly after it occurred.

In the new recording published by The Guardian, Slager can be heard apparently getting advice from another officer and laughing about an adrenaline rush minutes following the April 4 South Carolina fatal shooting that has sparked national outrage.

The senior officer urges Slager to write down his recollection of the incident in the clip. "By the time you get home, it would probably be a good idea to kind of jot down your thoughts on what happened. You know, once the adrenaline quits pumping," the unnamed officer is heard saying.
